Abstract
The invention discloses a processing method for a rotating shaft of a permanent magnet motor. The method comprises the steps of turning an excircle on a numerical control machine tool; leaving a 0.25 mm grinding allowance in the diameter direction of the rotating shaft during the turning treatment; clamping a workpiece with a clamping fixture on a radial drilling machine, upwards placing the to-be-processed end, arranging a drill jig on a shaft head in a sleeving manner, and carrying out drilling; carrying out inner hole processing after coarse grinding of the excricle on an exricle grinding machine; processing an internal spline through one of slotting, broaching and electric sparks; and after the internal spline is processed, accurately grinding the excircle to complete processing of the workpiece. According to the processing method for the rotating shaft of the permanent magnet motor provided by the embodiment of the invention, the processing accuracy of the rotating shaft can be guaranteed, and the requirements on the performance of a rotor and the operation performance of the motor are met.
Description
Technical field
The present invention relates to new-energy automobile manufacturing technology field, particularly relate to the processing side of the rotating shaft of a kind of magneto
Method.
Background technology
Along with the extensive application of rare-earth permanent magnet material-Ru-Fe-Mn alloy, magneto has simple in construction, operation because of it
Reliably, the advantage such as small in volume and be developed rapidly, can be widely used for new-energy automobile field.Rotating shaft is in motor
Strength member, plays support rotating parts, transmission moment, and determines the effect of rotational components and the relative position of stator,
Its processing method and processing precision direct influence rotor and the runnability of motor.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the invention provides turning of a kind of magneto
The processing method of axle, it is characterised in that comprise the steps:
Digit Control Machine Tool carries out turning to foreign round；
When carrying out described turning and processing, the diametric(al) in rotating shaft reserves grinding allowance 0.25mm；
With the clamping workpiece of mold on radial drilling machine, make one end that needs are processed upward, drill jig sleeve is bored on spindle nose
Cut；
Cylindrical grinder is placed on interior hole machined after corase grind cylindrical；
Use the processing method processing internal spline of slotting, broaching, electric spark thrin；
Process after described internal spline fine cylindrical again, complete the processing of workpiece.
Preferably, described step uses in the processing method processing internal spline of slotting, broaching, electric spark thrin, makes described
The hardness of internal spline is HRC35.
Beneficial effect:
The processing method of the rotating shaft of the magneto that the embodiment of the present invention provides, can ensure that the machining accuracy of rotating shaft, so that it is guaranteed that
The performance of rotor and the runnability requirement of motor.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
Embodiments of the invention disclose the processing method of the rotating shaft of a kind of magneto, comprise the steps:
Digit Control Machine Tool carries out turning to foreign round；
When carrying out described turning and processing, the diametric(al) in rotating shaft reserves grinding allowance 0.25mm；
With the clamping workpiece of mold on radial drilling machine, make one end that needs are processed upward, drill jig sleeve is bored on spindle nose
Cut；
Cylindrical grinder is placed on interior hole machined after corase grind cylindrical；
Use the processing method processing internal spline of slotting, broaching, electric spark thrin；
Process after described internal spline fine cylindrical again, complete the processing of workpiece.
Further, step uses in the processing method processing internal spline of slotting, broaching, electric spark thrin, makes institute
The hardness stating internal spline is HRC35.So, make the hardness that internal spline holding is higher, make the rotating shaft performance processed more preferable.
The processing method of the rotating shaft of the magneto that the embodiment of the present invention provides, can ensure that the machining accuracy of rotating shaft, thus
Guarantee the performance of rotor and the runnability requirement of motor.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
